When L.A. Confidential premiered in 1997 I was one of the few cinephiles that wasn't overcome with passion for it. I thought it too warm, actually. The happy(ish) ending threw me since most of the noir I was familiar with (not a wide sample I'm afraid) was much more nihilistic, rarely leaving the compromised heroes alive or free. It was the clear critical favorite in its year, though, so I've long wanted to reassess it and spend more time with it. I'm happy to report that I underestimated it the first time around. The screenplay with its hardboiled broad strokes dialogue and characterizations made more sense now that I'm more familiar with its tropes. But above all else it's a "wow" in execution from every department (but yes we're here to talk cinematography).
My clearest memories of the film were three: the smarmy gossip opening "on the QT and very hush hush", that I was enamored of both Russell Crowe and Kevin Spacey's performances, and the (literal) head-turning introduction of Lynn Bracken (Kim Basinger in her Oscar winning role) though it should surprise virtually no one who reads the Film Experience that the subplot of the Fleur de Lis girls "whores cut to look like movie stars" was the storyline I was initially most drawn to.
Whatever you desire.
